Foldable lampshade or lamp base adaptable for inexpensive mass production and configured for easy assembly without having to remove the lamp socket. The frame part comprises a pair of connected or separate complementary sections, substantially shaped as a mirror image of each other. The sheet-like part is a sheet or foil, optionally having concave and/or convex relief shapes and/or notched curves as ornaments, or folding aids, or mechanical connections elements or other structures such as cutouts. Embodiments, the at least one sheet-like part comprises a plurality of connected or separate sheets, such as a pair of parts. The sheet-like part, or parts thereof, is adapted for forming a circular or partly-circular contour, or other shape, on the frame and/or around the lamp. In some embodiments of the invention, the lampshade and lamp base are assembled (constructed) by folding the parts and connecting them by fasteners that are integrally formed with or attached to the parts that comprise the lampshade or lamp base (either on the flexible sheet parts and/or the frame part). Preferably, without limiting, the lampshade and lamp base may be assembled and disassembled without removing the lamp socket or bulb and without any tools by a person with no particular skill. For example, the assembly is carried out by interlocking elements shaped like snap fasteners or by hook and loop fasteners. In some embodiments, the fasteners are integral with the lampshade or lamp base, while in other embodiments the fasteners are attached to the lampshade or lamp base. In some embodiments of the invention, the frame part and/or sheet-like part are made of, or comprise, polymeric materials, by vacuum forming or cold forming. Optionally or alternatively, other fabrication methods are used, such as injection or molding. In an opened (unassembled) position, the lampshade and lamp base parts are substantially flat, requiring negligible storage space. |
